ABSTRACT

An improved structure of a side rail of an advertising panel includes a framework having four liftable side rails and four corner pedestals for connecting with these four side rails, and the corner pedestal is hollow and the L-shaped side of the corner pedestal is an opening. With this arrangements, these corner pedestals of the advertising panel are possible simply by lifting these side rails easily to change an advertising board fast and the latter is therefore more convenient for use to lift.

BACKGROUND OF THE INVENTION

[0001] The present invention relates to a design of a corner pedestalfor an advertising panel, and more particularly to a design of a cornerpedestal that enables a fast changing of simply with easy open and closeside rails of an advertising panel.

[0002] In the rapidly developed industrial and commercial society, thetraders have to decorate their product or put an advertisement in anadvertising medium in order to sell their product smoothly. Althoughthere are many kinds of advertising media, the best way to catchpeople's attention in t he darkness is the advertising panel. Thestructure of advertising panel and its translucent board used to be veryheavy. Now they have improved to be a light and thin structure. In orderto replace the conventional structure of the advertising panel, thetranslucent board of the advertising panel in various models are to someextent made light. Further, for the varied development of society, thetraders have to change a new advertisement in time for receiving of fullattention. Therefore, the advertisement board of the advertising panelshould be easy to change and be pleasing to the eye. The advertisingpanel is popular because of changeability. However, the conventionalstructure of the advertising panel has a lot of trouble to change itsadvertisement board.

[0003] Taiwan Patent Publication No.356275 discloses a conventionalstructure of an advertising panel. FIG. 3 is sectional view illustratingthe conventional structure of the advertising panel.

[0004]FIG. 4 is a partial enlarges view illustrating the conventionalstructure of the advertising panel. As shown in FIGS. 3 and 4, theadvertising panel includes a framework 10 arranged a plate at both thefront and rear end of the framework 10, and a light-guided board of aluminous body is installed between the front plate and the rear plate.The framework 10 is composed of several side rails 101 and a cornerpedestal 102. The side rails 101 are further composed of a front siderail 1011 and a rear side rail 1012. A slot plate 10111 is formed on oneside of the front side rail 1011. Several through holes 10112 arearranged in the slot plate 10111. A groove 10113 is formed on anotherside of the front side rail 1011. A front end of the groove 10113 isextending to the plate surface. A batten 103 having an inserted portionis tightly inserted into the groove 10113. An internal plate 10121 isformed on one side of the rear side rail 1012. A row of groove 10122 isfully arranged in the internal plate 10121. A fixed groove 10123 isformed on a flange of the internal plate 10121. The front side rail 1011is connected with the rear side rail 1012 and the slot plate 10111 isinserted into the fixed groove 10123 of the rear side rail 1012. Thegroove 10122 of the rear side rail 1012 is screwed to lock into thethrough hole 10112 of the front side rail 1011 by using a screw 104. Ajoint flange portion 10124 is formed in the inner side of the internalplate 10121 of the rear side rail 1012. A connecting pipe 1021 is formedat both side of a right angle framework 102. A positional groove 1022formed in the connecting pipe 1021 is then tightly inserted into thejoint flange portion 10124.

[0005] In the above described prior art, a screw 104 needed to beunloaded before dismounting or mounting the board, and then separate thefront side rail 1011 and the rear side rail 1012 for implementing thechange of the board. After the change of the board is completed, thebatten 103 is stuffed into the groove 10113 of the front side rail 1011again for fixing the board tightly. The change of the board wastes a lotof time. If there are numbers of the required change of the board, itgoes without saying that the cost of operation will be increased.

[0006] Moreover, please refer to FIGS. 5 and 6 illustrating anotherembodiment of the conventional advertising side rail. As shown in FIGS.5 and 6, the advertising panel includes a framework 20 which can belifted. A deforming elastic segment, not shown, is installed between aside rail 20 and a cover plate 201 to control the opening and closing ofthe cover plate 201. However, because the two end portions of the coverplate 201 is assumed a dip angle to connect with each other, the dipangle of the end portions will get stuck and against each other when thecover plate is opened for changing the advertising board. Therefore, theangle of opening the cover plate 201 will be reduced substantially andit will be inconvenient for workers to exchange and draw out theadvertising board.

[0007] In brief, the conventional advertising panel does not solve theproblem of changing an advertising board conveniently. It is thereforedesirable to develop a design of a corner pedestal for an advertisingpanel which is capable of opening and closing its side rail easily.

SUMMARY OF THE INVENTION

[0008] A primary object of the present invention is to provide animproved structure of a corner pedestal that enables a fast changing ofsimply with an easy open and close side rail of an advertising panel.

[0009] To achieve the above and other objects, an advertising panel ofthe present invention mainly includes a framework having four liftableside rails and four corner pedestals. These side rails can be liftedeasily and be connected to these corner pedestals. The corner pedestalis hollow in its internal part and the L-shaped side of the cornerpedestal is an opening which is used for connecting to these cornerpedestals. With the above arrangements, a corner pedestal of anadvertising panel is possible simply by lifting these side rails easilyto change an advertising board fast.

DETAIL DESCRIPTION OF THE REFERRED EMBODIMENTS

[0017] Please refer to FIG. 1 and FIG. 2 that shows a corner pedestal ofan advertising panel in an assembled state and a preferred embodiment ofthe present invention respectively. As shown, an advertising panelincludes a framework having four side rails 1 and four corner pedestals2, which is use for connecting to the corner pedestal 2.

[0018] The side rail 1 is connected to a cover plate 12 from an outerside of a U-shaped base 11. A deforming elastic segment 13 is installedbetween the base 11 and the cover plate 12 to control for opening andclosing the cover plate 12. The two inner side of the side railrespectively extending to lean against the plate surface may be used toclip various required board from both sides. Two lock holes 121 areprovided on the two side of the base 11.

[0019] The corner pedestal 2 like a rectangular figure is hollow in itsinternal part and the L-shaped side of the corner pedestal is an opening21. A lock plate 22 is formed from the two adjacent ends of theextending of the opening 21. A lock hole 221 is provided on the lockplate 22 corresponding to the lock hole 121 of the base 11 and a screw 3is locked the side rail 1 and the corner pedestal 2 to connect the endof the two side rails 1. A block slice 23 correspondingly formed fromthe two adjacent tops of the opening 21 is provided to make the coverplate 12 to stride against it.

[0020] In this manner, when the cover plate 12 is lifted upward, the endportions of the side rails will not get stuck and against each other. Inthe meantime, the advertising board will be also clipped and buckled bythe inward right angle of corner pedestal 2 and the clipping power ofthe cover plate 12. This is showed a great effect for fixing theadvertising board. With the above-described arrangements, a cornerpedestal of an advertising panel is possible simply by lifting theseside rails easily to change an advertising board fast and the latter istherefore more convenient for use.
